This invention relates to improvements in spray valves for oil engines. yThe especial ob 'ect of the'invention is to provide a more efficient and reliable spray I valve of the multiple jet type, whereby a substantially uniform amount of oil will be distributed to each orifice of' the multiple jet. My improvedisprayI valve is highly eilicient in all positions. as it may .be effectively used l with its longitudinal axis horizontal or`in any inclined position, as well as in a true vertical position.

Briefly stat-ed, the improvement includes means whereby the oil entering the spray l Valve casing has imparted thereto a whirling motion in a plane transverse to' the longitudinal axis of such casing, so as to maintain a practically even distribution of the oil l throughout an annular `chamber within such casing irrespective of its longitudinal position. Pressure air.4 admitted as usual, will thus be applied at, uniform pressure over the surface of the annular body of oil and the latter be distributed toeach lof the annularly arranged orifices of the multiple jet. The present arrangement also includes -means for intimately commingling the air and oil in itspassage to the multiple jet ori? ices, so thatv the fuel is delivered thereto 1n a properly atomized state torinjection into the combustion space of the engine as the valve opens. valve. when used in a horizontal or any inclined position, has all the advantages here- '35.t0fore obtained only in a spray valve designed for use with its) longitudinal axis in a true vertical position. To enable a full understanding of the invention to be had, a-detailed description of a valve embodying the invention in preferred and modiied forms will now be given in connection with the accompanying drawL ings, and the features forming the invention then be specifically pointed out in the claims. In the drawingsl I Figure 1 is a' longitudinal section -ot one preferred embodiment of theinvention mounted on a cylinder extension;

Figure 2 is an enlarged section on rthe line 22 of Fig. 1, with the cylinder extension omitted; Figure 3 is a partial view -similarto Fig.

41, showing a modified construction,

Figure 4. is an enlarged section on the line Thus, the improved spray' 4-4 of Fig. 3, with the cylinder extension omitted.

Figure 5 is a view similar' to Fig. 3,`sl'1oyv ing another modification.

Referring now to the drawings,- and particularly to Figs. 1 and 2. the spray valve casing 20 is shown as mounted in a cylinder extension A. Positioned centrally within the yalye lcasing-'20 is a valve spindle 21 carry-l ing at one end a conical valve plug` 22 arranged to rco-operate with an inclined seat which. in the present showing. is formed directly on the casing 20. At its opposite end'the spindle 2l passes through a stuiiing box 23 of usual construction. and on the portion outside thereof is encircled by a compression spring'24 taking against collars 25. 26, so as to normally hold the valve closed, the valve being shown as opened against the spring 24 by the usual lever D.

To insure equal distribution of the -oil to the iet orifices in the spray nozzle. `irrespective of the position of the 4spray valve. there is provided a member 1- which. for convenience in manufacture. may be. as shown.

.an exten-sion formed on the stuiiing box 23.

This member 1 surrounds the valve spindle 21 and is *secured in proper position by threaded engagement with a nozzlev tip 2 -pos itioue'd within the casing 20. In the nozzle tip 2 there are formed the usual ducts or iet ori tices which in the present showing converge toward their outlets.v and preferably lie approximately parallel with the outerl wall of the conicalnozzle tip. the oil entering the ducts 3 from annular ducts or chamber 1. The member 1. also. is shown as of section (Fig.l 2). but obviously mav be of any other shape `which willprovide either an annular chamber or series of longituis properly-positioned with respect to the valve casing 20 and the member 1 by prothe enlarged end of the member, the'pump.

supplying-oil to such chamber 'through con-v nection B. ',The annular chamberV 9 thus formed between the member 6 and the casing 20 receives the pressure airthrough the 4approximately rectangular shape in crossdinal passages 5. when enclosed in a cylindri. cal member such as 6.' This latter member ring be used, there is provided between the plates 11 and member 6 acircular. member 13, having a concave peripheral surface 14, to which oil is supplied under pressure through a tangential passage or passages 5. and a whirling motion of the body of oil around the member 13, in the groove 14, thus maintained. Only one tangential passage 15 is shown, and this usually will be found preferable, but it willv be understood that any number of such passages may be used as desired. Such whirling motion, according to the present showing, is of course in a plane at right angles to the longitudinal axis of the spray valve, and generates a centrifugal force which will hold the oil up against the action of gravity and-evenly distribute it over the openings 12 in the plates 11, although the valve be horizontal. Air entering through connection C will therefore be substantially evenly applied to the realin surface of the whirling bodyof oil, that is, the surface farthest from the spray nozzle, so that the air behind the body of oil drives it toward the spray nozzle, and as the oil moves through the atomizing `ring such airl will be intimately commingled with the oil as it reaches the annular chamber 4, from which it passes to all of the jet orifices or ducts 3 for delivery to the combustion space y of the engine when the valve 22 opens. The concave groove 14 forms a chamber which aids in retaining the'whirling body of oil in position for the action of the air thereon. which delivers the oil from the groove in a thin film past the edge of the grooved member 13.

In the modified spray` valve construction shown iny Fig. 3, the oil is admitted first to the annular chamber 16 and pressure air to a similar chamber 17. The oil then passes to the annular groove 18, formed in an enlargement on the end of a cylindrical member 19. Due to the tangential position ofthe passage 15 leading into chamber 18 from chamber 16 (Fig. 4), the whirling motion of the body of oil, described with referenceto Fig. 1. results, with a similar generation of centrifugal force sufficient to maintain such whirling body of oil evenly distributed throughout the space 18, irrespective'of the longitudinal position of the spray valve. Thus, as pressure air is admitted to chamber 17, a substantially uniform pressure of air will be applied over all the rear surface of the whirling body .of oil` and the latter be forced through the atomizer, where the air will be commingled with the oil and the fuel delivered in a finely atomized state to all of the ducts 3 for injection into the combustion space of the engine when the valve 22 opens.

Referring to the modification of Fig. 5,

the construction shown simplifies the arrangements of Figs. 1 and 3 by eliminating the members 6 and 19, respectively, of such figures. As shown in this modification the oil passage is formed directly in the guide sleeve 1a for the valve Spindle 21, the wall of such sleeve preferably being thickened at such point for this purpose, and such guide sleeve extending to and having threaded engagement with the nozzle tip as shown in Fig. 1. The passage 27, 4according to the present vmodification, conducts the oil to an annular chamber 28, which preferably is formed in a circular member 29 mounted on a reduced extension of guide sleeve 1". This chamber 28 may be conveniently closed on one side, except at the point where the passage 27 enters it, by an annular enlargement or head 30, the latter also serving to hold the member 29 firmly against the bottom of the cup-like member 31, the outer wall of which snugly fits the bore in the valve casing 20. The inner side wall ofthe member 31 preferably and as shown 1s slightly concaved, thus providing an annular chamber 32 to which the oil from cha1nber 28 is delivered by tangential passages 33. Asin the case of Figs. 1 and 3, the tangential arrangement of these passages 33 imparts a whirling motion to the oil within the annular chamber 32, so that the oil is evenly distributed with respect to the orifices 34. irrespective of the longitudinal position of the spray valve. Thus, as pressure an' 1s admitted to the annular space 35, a substantially uniform air pressure is applied over the whole rear surface of the whirling body of oil within the chamber 32, and the oil thereby forced through all ofthe orifices 34, and thence to t-he atomizer and combustion space, as above described.

It will be understood that the invention. 1s not to be limited to the particular type of spray valve shown, but that it may be used with other types of spray valves, and that modifications may be made in the means for distributing the oil in 'a uniform body for the action of the air, while still retaining the invention defined by the claims.
